Could vector type of poly_int and compile-time constants be enabled at the same time ?

[JojoR via Gcc]

Hi,

        I have a little know about for 'Sizes and offsets as runtime 
invariants’,

        and need to add vector types like V2SImode as compile-time constants
        with enabled vector types of runtime invariants.

        Could I enable two vector types at same time ?
        I guess it’s not allow :(

        Could anyone give me some hints ?

Thanks,

Jojo R
